Something doesn't look right on the X-Axis bearing mount. I'll be examining that carefully soon. Thanks for the other good ideas - I'll try some other circle sizes to see if the error scales up or not. Profiling in a circle is turning out to be more useful as a diagnostic than I thought. To...

It was a DIY project, made from spare parts many years ago. I bought it in September from the guy who built it. 48x32x8 movements. Typical gantry system. The Y-axis has two steppers (one slaved) with toothed belts. The X and Z axes are driven by single belted stepper motors. The X and Z...

Still getting my CNC router dialed in. Thanks to many forum members, for your help so far. https://canadianhobbymetalworkers.com/threads/motor-acceleration-between-master-slave.9626/#post-137423 With some free time over the holidays, I set about making sure it's well calibrated. Mostly it...

Good Karma indeed. Will you end up being one of guys who is better equipped at home than you are at work? With the addition of my CNC router, that is something I can say, this year. I'm not ashamed to brag.

Wayne Winters, owner of the land and airport in the early 00's when I flew, is getting up in years and probably hasn't found family willing to hand it down to. Land in that area is gaining in value rapidly, so even if there's interest in running the little airport, the economics probably...

OK fixed that. Found another problem: The slave-motor's A-axis prox-sensor was 3/16" back from the stop compared to its counterpart Y-axis sensor. I found this problem because re-referencing the Y-axis to home didn't zero-out the A-axis and its motor kept turning. Loud noises! Shifted the prox...

Nice work! I loved my time flying DA-20's back in the year 2000 to 2001. I blew a bit more than 10k on my PPL and the typical story - life happened and I haven't flown much since. I couldn't help but look up C-FZRE just in case it's a DA-20 I've run across before. It isn't, but it was...

Hello, I've been enjoying my CNC router table since getting it several months ago. The holidays have given me time to try some more ambitious projects, and get tighter tolerances on parts. I knew this is when limitations or problems would show up, but no disasters so far...

Oh, I just blew my spending money on a router!
